# d384ad6b	13-Nov-2019	joanlluch <[email protected]>	[TargetLowering][DAGCombine][MSP430] Shift Amount Threshold in DAGCombine (4) Summary: Replaces ``` unsigned getShiftAmountThreshold(EVT VT) ``` by ``` bool shouldAvoidTransformToShift(EVT VT, unsi [TargetLowering][DAGCombine][MSP430] Shift Amount Threshold in DAGCombine (4) Summary: Replaces ``` unsigned getShiftAmountThreshold(EVT VT) ``` by ``` bool shouldAvoidTransformToShift(EVT VT, unsigned amount) ``` thus giving more flexibility for targets to decide whether particular shift amounts must be considered expensive or not. Updates the MSP430 target with a custom implementation. This continues D69116, D69120, D69326 and updates them, so all of them must be committed before this. Existing tests apply, a few more have been added.
